I make height map patterns for CNC carving machines and these are some of the latest project I had done. Most of the stuff I've been doing is military emblms and patches. One of these is a photo of a real carving that someone sent me. I do a lot of vector paths in Illustrator because of the duplicating and rotating capabilities then save layers as photoshop file and open them in gimp to do all the editing and gradients etc.

Thats very cool! How are you making these? I'm assuming some sort of 3D rendering program?

Well I just do an emboss filter and then colorize it for display. An actual height map image would look like this.

Woops, never worked with CNC milling and assumed it would work off of a 3d rendering.

Still very cool! :clap

They have software that converts bitmap to g code. I use a carvewright machine which imports bitmap right into the software.

Cool stuff. Can you create depth-maps form any image?

Excellent work PegLeg. I'd love to see what you do with that eagle height map.

Hi Wallace

A depth map, height map or relief pattern is all the same think. It's like 3D on a shallow plane. I guess anything that would look good as a shallow relief would work.

looks great. Do you have a tutorial for us?
I want to learn how to make the height map, too.
thanks.

@ frankleng, If you read through this thread, there is quite a few explanations about height map.

Hi frankleng

There are so many techniques that I use to make height maps that I can't explain them all. When I make one I sit and think for a while about what I'm going to do. I can't teach someone how to do that. I know I've tried.

Basically I define the X and Y axis using the pen tool. With the path visible I [Shift+V] to make it a selection. Then I [Shift+Q] into quickmask mode and do a [Alt+C then T and hit OK with the mouse] To flatten the edges. Then exit Quick Mask mode [Shift+Q]. Then on a layer I make a layer mask out of the selection [H then Enter after choosing [by Selection]].

With all the layers with layer masks, I then draw or make gradients inside of each mask. If you turn the layer mode to Darken only then each greyscale layer will blend into each other nicely.

And to get the height of each layer the way I want it I sometimes duplicate a layer (so I don't ruin the original) and then slide the left node up and or the right node down of the curves dialog box.

I hope you don't mind but I couldn't resist putting this one through Bryce.

Hi Erisian

That looks just like the image I carved out in MDF and painted with a bronze hammered metal paint.

These are awesome PegLeg; bet you make the big bucks doing these. Thanks for sharing your stuff with us. I just wish there was a quick and easy way to create depthmaps from single phones but the only ones I've see have been both slow and not really accurate enough for my taste. :)
